Way to disable 'Warning: Limited encoding support'?

[vszakats]

This warning is now permanently shown when building without iconv. While understanding the drawbacks, I'd argue that there may be cases/platforms where building against iconv isn't practical or isn't necessary. E.g. on Windows, building iconv is a challenge and even when done, it's a large dependency that needs to be shipped around. In cases where minizip2 is used in a controlled environment with known, or pure-ASCII filenames, it can work well without codepage conversion.

It'd be nice to have a way to avoid this warning and silently fall back to the transparent strncpy() method.

Do you have any suggestions? Maybe we should only mention this in CMake?

[vszakats]

Moving that (a.) to CMake would be nice, or, (b.) implement a #define specifically to enable the non-iconv branch (e.g. MZ_ENCODING_TRANSPARENT), or (c.) a HAVE_NO_ICONV #define which would have the same effect as no HAVE_ICONV, but would suppress the warning.

[ My preference is (a.), (c.), (b.) ]

I think we should do CMake too. Do you want to do a PR?

[vszakats]

I'm not a "CMake-person", so I'd trust yours much better for this solution.
